They are just dead, right. Or are they?
the hairs on some areas will stop growing after about 2 inches. And as soon as I cut them off, they will grow again to 2 inches and stop. How?

They don’t. There’s wear and tear on them and any section of hair will survive X amount of time. It grows out more or less constantly and once it’s too old and worn, that section will break off leaving your hair that long. Different hairs, like arm hair or head hair, will have different strength, durability, and growth rate. But both will behave the same: Grow at a constant rate and the damaged ends break off.
